The ThighSlide object represents a two-point slide setup (see PointSlide) and a spherical thigh volume object that bounding-volume constrains the Bind null. The collection of guide objects passed to MakeThighSlide determines the position of the slide, and the proportions of the thigh volume.

The guide collection contains 5 objects. The first two objects are to position the top and bottom control objects of the slide. The bind point is the midpoint between these two objects, and also determines the center of the thigh volume. The third object is the bottom of the hip, and determines the radius of the thigh volume. The fourth and fifth objects are the base and tip of the thigh bone (leg and knee joints). The vector created by these two points defines the thigh bone and is used to align the thigh volume with the thigh bone.
